Alignment of full-page scores in text documents

[Urs Liska]

Hi all,

I'm trying to figure out the best setting for page margins for mixed 
text/music documents. The task is to automatically set the margins in 
LilyPond depending on a LaTeX document where full-page scores are included.

We have the horizontal margins more or less fixed, by default LilyPond's 
staff symbol will exactly match LaTeX's linewidth. When naively setting 
LilyPond's vertical margins to those of the text the result is 
(expectedly) rather ppor, as you can see here: 
https://github.com/jperon/lyluatex/issues/29#issuecomment-361159545. 
What I would basically want to achieve is mathing the outermost *staff 
lines* with the text's type area.

When manually trying different values I found that I would like the 
topmost staffline align not with the actual margin but the X-height of 
the corresponding text. This can be seen here: 
https://github.com/jperon/lyluatex/issues/29#issuecomment-361162799

On that same image the bottom staff line is aligned to the baseline of 
the text, and I'm not sure if that is the right choice. Somehow the 
score visually looks lower than the text, and I wonder whether there 
should be a similar amount of padding like at the top margin. But of 
course there is no "natural" reference point here.

What is your opinion on this issue?
